The place is in the best possible location in Bangkok with Siam Paragon, Lumphini Park, the BTS and many restaurants just next to it. It is neatly designed, well equipped and feels like home at first sight. The view from the balcony is amazing and the beds are comfortable, basically, it is an oasis in the hustle and bustle of Bangkok. The pool on the 5th floor is great for swimming as it is quite wide-stretched and deep, there is also a nice gym and a running/walking track around the building.
Hermann is a lovely host and the communication, check-in etc. was without any problems. We really didn't miss anything and will definitely stay here a second time when we travel to Bangkok again!
